Trait ErrorCounters 

pub unsafe trait ErrorCounters {
    type CDescriptionsArray: AsRef<[vlib_error_desc_t]>;

    const C_DESCRIPTIONS: Self::CDescriptionsArray;

    // Required method
    fn into_u16(self) -> u16;
}

Trait for defining error counters of a VPP node

Typically this trait is implemented automatically using the vpp_plugin_macros::ErrorCounters derive macro.

Safety

• The length of C_DESCRIPTIONS must be greater than the maximum value that into_u16 can return (i.e. if implemented for an enum, it should match number of discriminators, and there are no gaps in the discriminator values).
• Each entry in C_DESCRIPTIONS:
  • name must be a valid nul-terminated string.
  • description must be either null or a valid nul-terminated string.

Required Associated Constants

const C_DESCRIPTIONS: Self::CDescriptionsArray

Array of C descriptions of the errors indexed by Self::into_u16

Required Associated Types

type CDescriptionsArray: AsRef<[vlib_error_desc_t]>

Array type for Self::C_DESCRIPTIONS

Required Methods

fn into_u16(self) -> u16

The u16 value of this next node

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
